查询词典 electrons

The main advantages of using the Dirac equation in a description of electrons are the following:(1) The Dirac equation is compatible with the theory of relativity (2) it describes the spin of the electron and its magnetic moment in a completely natural way.

在电子的描述中用Dirac方程描述主要优势有：（1）Diarc方程同相对论理论是一致的；（2）它很自然地描写了电子自旋和自旋磁矩。

At last, we are concerned with the global existence and asymptotic behavior of smooth solution to the initial boundary value problem for the bipolar hydrodynamic model with the Neumann and Dirichlet boundary condition in the one-dimensional case, respectively. The difficulties from the coupled action between electrons and holes are carefully dealt with.

另外，本文也深入研究一维空间双极半导体流体动力学模型初边值问题光滑解的整体存在性及其衰减性，分别讨论了两类在实际应用中重要的边值条件，克服了由于电子和空穴之间的耦合作用所带来的困难。

The energy levels of electrons and holes inGaxIni-xAs/GaInAsP strained quantum wells and their dispersion relations arealso obtained.

利用S.L.Chuang提出的传递矩阵法计算了GaInAs/GaInAsP应变量子阱的能带结构及色散关系。

Accordingly, the dot texture shown does not map individual eletrons; instead, it suggests the cloud of electrical charge the electrons paint out during their symmetrical but untrackable quantum pattern of motion.

相应地，这里所展示的点状图并非是对单个电子的图示；相反，这张图展示了电子在做对称但不确定的量子式的运动时所绘出的电场。

The next bond is a double bond this happens when two pairs of electrons share.

第二种为双键，有两对共用电子对时则形成双键。

There are much more electrons that can be stored in the double layer than single layer nanocrystal memory device.

双层的奈米点记忆体比起单层的记忆体有更多的电子储存在里面。

In this paper,the diffraction and the interference of electrons from a double slit and a multi-slit have been analyzed by quantum theory, and the results are in keeping with light s.

运用量子理论分析了电子双缝、多缝的衍射、干涉，与光的双缝、多缝的衍射、干涉完全一致。

The drift velocity of electrons d...

电子的漂移速度则随温度升高而降低。

The drift velocity of electrons decreases with increasing temperature.

电子的漂移速度则随温度升高而降低。

The influence of time on displacement was obtained, and the curve slope was approximate equal to drift velocity of electrons.

绘制了电子的位移与时间关系图，得到的曲线斜率可近似认为是漂移速度。

This immediately brings us to the next part of this article: creating an output "replace function".

下面进入文章的第二部分：建立一个"缓存处理函数"。

He was elected as an International Ornithological Committee member in 2002 during the 24th IOC held in Beijing.

现为中国鸟类学会理事和WPA 专家组成员。2002年被推选为国际鸟类委员会委员。
